Right, so in that case, they can't trust their ISP ;)

I don't know Witopia, and they're not even covered in

From what I see on the Web, they're similar to HideMyAss. And I'd trust
them about as much. I recommend that your friend pick one from the
TorrentFreak review.

It's both, I think. If the VPN fully disconnects and then reconnects, I
believe that it uses a new Tor circuit. If the OpenVPN client-server
connection is merely refreshed, however, I suspect that the Tor circuit
doesn't change.
